We evaluated the effect of anticoagulant (lithium heparin, sodium heparin, or none) and type of autoanalyzer on selected blood biochemical values of the loggerhead sea turtle (Caretta caretta). More differences were observed between the analytes in serum and those in the 2 types of plasma than were observed between the 2 types of plasma. Differences in electrolyte concentrations were not significant when plasma from sodium-heparinized blood was compared with plasma from lithium-heparinized blood. Serum is not recommended for reptilian studies because clot formation is unpredictable and because the time required for clotting may allow substantial changes in the chemical composition of the sample. For most determinants, values varied more between the 2 types of autoanalyzers than among the 3 anticoagulant treatments. These sources of variation must be considered when performing comparative studies.
